Abstract (en)

[origin: EP4137765A1] A volatilization device and a storage device. The volatilization device comprises: a shell (100) having a cavity, an air outlet (301) communicated with the cavity being formed on the shell (100); and a color change member (800) fixed on the shell (100). One side of the color change member (800) is exposed to the cavity, the other side of the color change member (800) can be seen from the outer wall of the shell (100), and the color change member (800) changes color according to the concentration of a target gas in the cavity. The storage device comprises a box (400) and the volatilization device, and the shell (100) is fixed in the box (400). The color change member (800) is fixed on the shell (100), one side of the color change member (800) is exposed to the cavity of the shell (100), the other side of the color change member (800) can be seen from the outer wall of the shell (100), and a user thus can determine, by observing the color change of the color change member (800), the validity of an item to be stored in the cavity, helping the user in in-time replacing.
